I was reading the announcement from Layer7 about its ‘SOA-in-a-box’ for IBM mainframe users, and a number of things struck me.
First, I am SO PLEASED to see someone remembering that CICS is not the only mainframe transaction processing environment in use today. A significant number of large enterprises, particularly in the finance industry, use IBM’s IMS transaction processing system instead. With the strength and penetration of CICS in mainframe enterprises, it sometimes seems like these users have become the forgotten tribe, but investments in IMS are still huge in anyone’s numbers and it is a smart move to cater to them. I am sure that the fact that this solution serves IMS as well as CICS users will be a big plus.
The other point that struck me was that I have felt for some time that, with the security/intrusion detection/firewall/identity management market seeing such a shift to security appliances, it was time vendors thought of piggy-backing functionality onto these platforms. Of course, one reason for having an appliance is to provide a dedicated environment to address issues such as security, but in truth these appliances are rarely used to anywhere near capacity. Therefore it makes a lot of sense to optimize the use of the available processing power rather than slavishly locking it away where it can;t help anyone.
Finally, I have to admit my first reaction to this announcement was to worry about how good connectivity would be to the mainframe. Dealing with mainframes is an arcane area, and I was not aware that Layer7 had any special expertise or credentials here, but I see that GT Software is apparently providing the mainframe integration piece. This makes me a lot happier, since this company has been dealing with mainframes for 20 years. In fact, Lustratus did a review recently on GT Software’s Ivory mainframe SOA tool, which is apparently what is included in the Layer7 box.
Anyway, on behalf of all those IMS users out there, thanks Layer7!
